Dr. Mihails Arhangelskis

I have received my undergraduate degrees (BA and MSCi) from the University of Cambridge, UK. For my Master's and PhD I have worked under the supervision of Professor William Jones, getting exposed to an exciting world of organic solid state chemistry and crystal engineering. The PhD project concerned the application of periodic DFT calculations to predict and rationalize the optical properties of organic multicomponent molecular crystals (cocrystals). In the course of this project I developed a method for the prediction of solid-state luminescence spectra of organic crystals, using periodic time-dependent density functional theory (TD-DFT).
Following the PhD (end of 2015), I enjoyed a visit to the group of Professor Krzysztof Woźniak (Department of Chemistry, University of Warsaw), where I explored the application of high resolution X-ray diffraction measurements as a method to visualize experimental charge density in crystals.
Between 2016 and 2019 I have worked as a postdoctoral fellow in the group of Professor Tomislav Friščić at McGill University. As a member of a vibrant experimental community, I enjoy exposure to a broad variety of projects, which benefit from theoretical simulations. My activities are evenly divided between simulations for metal-organic frameworks (MOFs) and organic molecular crystals.

Ivana Brekalo

Ivana hails from Croatia, where she finished her Bachelor and Master studies. After a short stint in pharmaceutical industry, she went to do her PhD at Georgetown University in Washington, DC, USA, under the supervision of Dr K. Travis Holman (Georgetown Univ.), and Dr. Tomislav Friščić (McGill University, Montreal, Canada). Currently she is visiting our group thanks to the support from NAWA Ulam Programme. Her focus is on mechanochemistry of porous materials, including MOFs, porous molecular solids, and supramolecular porous solids. Ivana is passionate about science communication and outreach, baking, ballroom dancing, and boardgames.

Yizhi Xu

My name is Yizhi (Catherine) Xu and I came from Shanghai, China. In 2013, I moved to the UK and started to study in Yeovil College, where I did my A-levels in Chemistry, Maths and Further Maths. I obtained my MChem (Hons) degree at the University of Manchester, where I completed my Master’s research projects in Manchester Institute of Biotechnology in Prof. Paul Popelier’s lab. The research focused on the development an application of an in silico pKa prediction tool called AIBL-pKa, which employs equilibrium bond lengths derived from Density Functional Theory. In 2020, I started my PhD in the University of Warsaw under the supervision of Dr. Mihails Arhangelskis. My research interest is currently focused on using periodic DFT for metal-organic frameworks (MOFs) predictions, as well as performing MOF synthesis mechanochemically. When I am not doing chemistry, I enjoy exercising, playing violin and travelling to new places.

I am Lavanya from Tamil Nadu, India. I have completed my undergraduate and postgraduate studies in general chemistry from PSGR Krishnammal College for women in Tamil Nadu, India. I have completed my master’s research project in Dr. M. Nethaji’s lab, Inorganic and physical chemistry department, Indian Institute of Science (IISc), Bangalore. I then continued as a project assistant in the same department for a year. Then as a project associate, I worked at Prof. S. A. Shivashankar’s lab in the Center for Nano-Science and Engineering department, IISc. My research experience at IISc includes, pharmaceutical co-crystals, Luminescent materials based on non-bonding interactions in B=N chromophore materials and metal oxide thin films.
I joined as a PhD student in Dr. Mihails Arhangelskis group in 2021 and currently focused on electron density analysis of organic cocrystals and modification of luminescent properties in organic materials based on supramolecular architecture.
Crystallography is among the things that keep me excited, it is magic that I am fascinated about. In my free time I enjoy dancing, drawing and exploring historical places.
